Support for `keyring` in runtimes #2044

michalkucharczyk · 2023-10-26T14:00:32Z

This functionality is required for #1984.

This PR enables sp-keyring in no-std environments, allowing to generate the public key (e.g. AccountKeyring::Alice.public().to_ss58check()), which can be later used in the any of built-in runtime-genesis-config variant.

The proposal is as follows:

expose core::Pair trait in no-std,
full_crypto feature enables sign method,
std feature enables generate_with_phrase and generate methods (randomness is required),
All other functionality, currently gated by full_crypto will be available unconditionally (no-std):
-- from_string
-- from_string_with_seed
-- from seed
-- from_seed_slice
-- from_phrase
-- derive
-- verify

Depends on rust-bitcoin/rust-bip39#57

it is still not working, I am getting compilation error (for rococo runtime, substrate-test-runtime works fine):

Looks like we have problem with std (which is pulled by digest which is probably pulled by schnorkel).

This will require to add Keyring support into runtime:

Oh? We take the string "Alice", turn it into a secret key, which somehow pulls in some name of the chain, and then put the public key into the genesis config?

I'd expect this adds considerable code to the runtime, like the 32kb basepoint table. I'm unsure how curve25519-dalek does backend selection now, but once upon a time it was manual.

Anyways schnorrkel pulls in digest through curve25519-dalek and sha2, which could be optional probably, but schnorrkel does not obviously propagate std to either.

https://github.com/search?q=repo%3Aw3f%2Fschnorrkel+path%3A%2F%5Esrc%5C%2F%2F+digest&type=code

I'd expect digest gets pulled in a few othr places, like ss58 maybe.

Yeah, we don't need secret key, true. Some other potential ways to go around:

hard-coding the public keys bytes in chainspec + adding some some comment on the origin of the key,
adding the public-keys-db crate that contains common keys used in chainspecs (so we can still refer them by URI string).

burdges · 2023-10-27T08:45:55Z

we don't need secret key, true.

You need them for derivation since presumably "Alice" is the secret key.

hard-coding the public keys bytes in chainspec + adding some some comment on the origin of the key,

You could just add a check in the host that they agree I guess.

It's not ideal to expose signing in the runtime since then people might think they can use it.

Looking good so far.

Can we not just disable the std feature for it?

It looks like tiny-bip39 is not ready for no-std:

Is there a good no-std alternative for this?

Is there a good no-std alternative for this?

Maybe the original crate bip39 this was forked from? Though, I don't know why it was forked.

@maciejhirsz can you shed some light on why you forked it?

Do you know what backend flags curve25519-dalek etc require for the runtime?

michalkucharczyk · 2023-10-30T15:07:21Z

Do you know what backend flags curve25519-dalek etc require for the runtime?

No. This particular one curve25519-dalek is not pulled-in explicitly.
It is pulled by:

ed25519-zebra
schnorrkel

For schnorrkel (which now is at v0.9.1) I assumed that the same feature set would work for runtime and std: "preaudit_deprecated", "u64_backend"

ed25519-zebra goes with no-default-features for runtime.

Do you recommend any adjustment here?

I've no idea.. A while back, curve25519-dalek got much better at autodetection, which afaik solved all native issues. I'm not sure what happens in wasm though. Anyways you've watched it actually work? No bugs appear?

I don't have any heavy tests to cross-check keys generation. Simple, naive shot seems to work fine - basically it is all we need.

@michalkucharczyk we can not merge this with git dependencies. This will break crates.io releases.

bkchr · 2024-03-11T10:45:44Z

We are actually working on getting rid off them: #2922

Must of them are currently either removed at release manually or are being in crates that we don't have released right now. Nothing of that applies here.

michalkucharczyk · 2024-03-11T11:20:42Z

@bkchr do you think I should create release on crates.io using this fork https://github.com/michalkucharczyk/rust-bip39 ?

There are two pending PRs in original repo, but things seems to be stuck there:
rust-bitcoin/rust-bip39#64
rust-bitcoin/rust-bip39#57

bkchr · 2024-03-11T11:34:20Z

Personally I'm not a big fan of this. The problem being that releases put onto crates.io will stay there forever.

However, I see that there is no movement. If you like, release it on your own. But please monitor and switch back to upstream when they have finished the release.

This PR provides simple address uri parser which allows to get rid of _regex_ which was used to parse the address uri, what in turns allows to remove lazy_static. Three regular expressions (`SS58_REGEX`,`SECRET_PHRASE_REGEX`,`JUNCTION_REGEX`) were replaced with the parser which unifies all of them. The new parser does not support Unicode, it is ASCII only.
